PI3K/mTOR/AKT Signaling Pathway01:22

PI3K/mTOR/AKT Signaling Pathway

6.1K
The mammalian target of rapamycin  (mTOR) is a serine/threonine kinase that regulates growth, proliferation, and cell survival in response to hormones, growth factors, or nutrient availability. This kinase exists in two structurally and functionally distinct forms: mTOR complex 1  (mTORC1) and mTOR complex 2  (mTORC2). The first form (mTORC1) is composed of a rapamycin-sensitive Raptor and proline-rich Akt substrate, PRAS40. In contrast,  mTORC2 consists of a...

mTOR Signaling and Cancer Progression

5.0K
The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.
The mTOR pathway or the...

cAMP-dependent Protein Kinase Pathways

8.9K
Cyclic Adenosine Monophosphate (cAMP) is an essential second messenger that activates protein kinase A (PKA) and regulates various biological processes. A single epinephrine molecule binds to GPCR and activates several heterotrimeric G proteins, each stimulating multiple adenylyl cyclase, amplifying the signal, and synthesizing large numbers of cAMP molecules. Small changes in cAMP concentration affect PKA activity. The binding of four cAMP molecules induces a conformational change in PKA,...

Mitochondria01:37

Mitochondria

21.1K
Mitochondria are eukaryotic cellular organelles that are known to produce energy through a process called oxidative phosphorylation. Besides their primary function, mitochondria are involved in various cellular processes, including cell growth, differentiation, signaling, metabolism, and senescence. Age-related changes cause a decline in mitochondrial quality and integrity due to increased mitochondrial mutations and oxidative damage. Thus, aging can severely impact mitochondrial functions,...

Electron Transport Chain: Complex I and II

19.4K
The mitochondrial electron transport chain (ETC) is the main energy generation system in the eukaryotic cells. However, mitochondria also produce cytotoxic reactive oxygen species (ROS) due to the large electron flow during oxidative phosphorylation. While Complex I is one of the primary sources of superoxide radicals, ROS production by Complex II is uncommon and may only be observed in cancer cells with mutated complexes.
ROS generation is regulated and maintained at moderate levels necessary...

Background:

  • Chronic, age-associated diseases are a major global health challenge, intensified by an aging population.
  • Research into aging biology has identified conserved gene networks that regulate aging and can be targeted for disease prevention.
  • Dietary restriction (DR) and metformin are examples of interventions that extend healthy lifespan and reduce chronic disease incidence.

Purpose of the Study:

  • To summarize the role of AMP-activated protein kinase (AMPK) in aging.
  • To explain how AMPK functions within a network of nutrient sensors.

Main Methods:

  • Review of existing literature on aging biology and nutrient-sensing pathways.
  • Analysis of the downstream effects of pro-longevity interventions.
  • Focus on the network involving AMPK, mTOR, IIS, and sirtuins.

Main Results:

  • AMP-activated protein kinase (AMPK) is a key player downstream of interventions like dietary restriction and metformin.
  • AMPK acts within a core network of nutrient sensors (mTOR, IIS, sirtuins) that regulate aging.
  • Interventions targeting this network influence cellular and physiological processes crucial for healthy aging.

Conclusions:

  • AMP-activated protein kinase (AMPK) is a central mediator of pro-longevity interventions.
  • Understanding AMPK's role in nutrient sensing is critical for developing strategies to combat age-associated diseases.
  • Targeting the AMPK-centric nutrient-sensing network holds promise for extending healthspan and improving quality of life in aging populations.
